Product Overview

The MCP19119-E/MQ is a highly integrated mixed signal analog current-mode Pulse Width Modulation (PWM) Controller with an integrated microcontroller core for synchronous DC/DC step-down applications. Since the MCP19119 uses traditional analog control circuitry to regulate the output of the DC/DC converter, the integration of the PIC® microcontroller mid-range core is used to provide complete customization of device operating parameters, start-up and shutdown profiles, protection levels and fault handling procedures. The MCP19119 is designed to efficiently operate from a single 4.5 to 40V supply. It features integrated synchronous drivers, bootstrap device, internal linear regulator and 4kW nonvolatile memory. After initial device configuration using Microchip's MPLAB® X Integrated Development Environment (IDE) software, the PMBus or I²C can be used by a host to communicate with, or modify, the operation of the MCP19119. Two internal linear regulators generate two 5V rails.
